yes it is an argentinian dogo, >I don´t know if pure ornot, ´cause aint´got no idea about the parents, but if U ask because of the decolouration of the nose, don´t worry. hope 2 be ussefull bye and wellcome

According to me... it seems more a dogo that an am bull... even if, hardly sight the pic, the doubt had come me.. even the head is a little "brachicelafa", wider that long, instead in the dogos it has to be mesocefala, the head of the same length of the face. It would need to see a pic of the head, in profile and even to imagine the skull-facial aces. Forgive me but I don't succeed in translating Brachicefalo and Mesocefalo in English.. Help me!!
